fix: apply CodeRabbit recommendations for hooks support

- Honor GROQ_NO_LOCAL_HOOKS environment variable in getHooksConfig()
- Anchor local config at project root instead of current working directory
- Fix getHooksConfig() call to use getActiveHooks() in hooks command
- Fix getMergedConfig() to properly merge hooks using special merge rules
